Forensic pathologist Shawn Parcells speaks during a news conference to share preliminary results of a second autopsy done on Michael Brown Monday, Aug. 18, 2014, in St. Louis County, Mo. The independent autopsy shows 18-year-old Michael Brown was shot at least six times, and Parcells, who assisted former New York City chief medical examiner Dr. Michael Baden during the autopsy, said a graze wound on Brown's right arm could have occurred in several ways.
